Fast & Fabulous Dark Chocolate Fudge

This dark chocolate fudge skips every traditional candy-making headache and comes together in a microwave in about 3 minutes of cooking. No candy thermometer, no soft-ball stage testing, no fear of crystallization. The corn syrup is doing real work here: it inhibits sugar crystals from forming, which is how you get smooth, creamy fudge instead of the gritty kind.

Evaporated milk and corn syrup go in the microwave together, then chocolate chips melt right into the hot mixture. Powdered sugar (already finely ground, so it dissolves instantly) goes in next with vanilla and chopped walnuts. A few minutes of vigorous stirring with a wooden spoon brings the fudge from glossy and loose to thick and dense, which is exactly when it’s ready to scrape into the pan.

A two-hour fridge chill firms it into clean, sliceable squares. Twenty-five small pieces from one 8-inch pan, perfect for cookie tins, gift bags, or just keeping in the fridge for chocolate emergencies.

Pro Tips

• Line the pan with plastic wrap as written. The fudge releases cleanly in one slab, and you can cut it on a cutting board instead of digging it out of the pan.
• Stir vigorously after adding the powdered sugar. The beating is what gives microwave fudge its proper dense, slightly chewy texture; stop too soon and it stays loose.
• Use a 3-quart bowl, not a smaller one. The hot mixture bubbles up significantly in the microwave; a small bowl will boil over.
• Toast the walnuts for 5 minutes in a dry skillet first. Untoasted walnuts taste flat against the rich chocolate.

Variations

• Swap walnuts for pecans, almonds, or skip the nuts for a smooth fudge.
• Use bittersweet 60% chocolate chips instead of semisweet for a more sophisticated, less sweet version.
• Stir in mini marshmallows just before pouring into the pan for a rocky-road style fudge.
